What does natural mean?
not made by people.
what does manufactured mean?
made by people
what is a mass structure?
A mass structure is made by pilling up materials into a particular shape
what is one advantage for a mass structure?
a mass structure can be held in place by it's own weight
what are 3 out of 4 key elements to avoid failure?
1) Must be heavy to hold it's own weight 2) must be anchored firmly 3) must be thick enough so it
can't be pushed out of place
what is the last of the 4 key elements to avoid failure
Must be heavy enough so it can't be pushed out of place.
what are load bearing walls?
load bearing walls are walls that support the load of the building
what are partition walls?
they are walls that divide up the space inside the building
what are examples of shell structures?
igloos, turtle shells
what are problems with shell structures?
they are small, and they can only be built in a specific location
what does function mean?
a structure or objects main purpose, its created design
what type of functions are there?
Containing, transporting, sheltering, supporting, lifting, fastening, separating,
communicating, breaking, holding
what does balance mean?
balance is used as a measuring device. it compares masses.
what is an external force?
on structure. stresses that act on a structure from the outside
what is a dead load and a live load?
a dead load is a permanent force acting on a structure and a live load is a changing force that
acts on the object
what is tensions force and tensile strength?
torsion force is the force that occurs when an object is stretched. Tensile strength measures
the largest tension force.
what is shear force and shear strength?
Shear force is a force that when applied will tear apart. shear strength is a materials ability
to resist shear force.
what is torsion force?
torsion forces are forces that cause an object an object to twist. (torsion strength is the
ability for an object to resist twisting.)
what are the 3 key methods to help withstand forces?
1) Distribute the load 2) Direct the forces along angled components 3) Shape the parts to
withstand the specific type of force acting object
